Popular Abstract in Swedish Benskörhet (osteoporos) är en sjukdom, som leder till att benstommen förlorar en del av sitt kalkinnehåll och sin styrka. Benbrott kan därigenom uppstå spontant eller vid lättare påfrestningar. Gastrektomi (kirurgiskt avlägsnade av magsäcken, GX) och ovariektomi (kirurgisk avlägsnade av äggstockarna, OVX) leder till benskörhet hos människa såväl som hos försöksdjur. MedBoth ovariectomy (OVX) and gastrectomy (GX) cause osteopenia in several animal species including humans. While the effect of OVX has been ascribed to estrogen deficiency, the underlying mechanism behind GX-induced osteopenia is poorly understood. Nutritional deficiencies, including lack of calcium and vitamin D, have been claimed to cause the osteopenia induced by GX. This thesis attempts to clari

Popular Abstract in Swedish Ben, brosk och mjukvävnad (utgörs av den tvärstrimmiga muskulaturen, fettväv och fibrös bindväv, men också av det perifera nervsystemet) är vävnader av mesenkymalt eller neuroektodermalt ursprung. De flesta tumörer som uppstår i dessa vävnader är godartade och blir därför ofta inte föremål för behandling, vilket gör det svårt att uppskatta incidensen i befolkningen. EnlBone and soft tissue tumors (BSTT) constitute a heterogeneous group of neoplasms of mesenchymal and neuroectodermal origin. Although many BSTT are rare, it has become clear that BSTT are characterized by recurrent acquired chromosomal aberrations, and the general aim of this thesis have been to apply molecular genetic and molecular cytogenetic techniques to further characterize recurrent breakpoin

Human antibodies generated in vitro may be highly valuable for diagnostic and therapeutic purposes. For a long time most human antibodies produced in vitro have been of the IgM isotype with rather low affinities. In this thesis a method for production of IgG switched antigen-specific human antibodies is presented. This is a two step protocol, in which the first step is a selection procedure of don

Popular Abstract in Swedish Syftet med föreliggande undersökningar var att söka nå en mer fullständig kunskap om barn och ungas eldsanläggelse; att undersöka hur frekvent förekommande det är, samt om det, i experimentella studier, kan relateras till frustration eller leda och till personlighetsdrag som optimism, pessimism och kreativitet. Avhandlingen består av fyra studier, två intervjuundersökniThe purpose of the present investigations was to obtain a more comprehensive view of fire setting by children and adolescents; to explore the prevalence of the phenomenon; whether or not it experimentally may be related to frustration or boredom and to examine the role of personality traits such as optimism, pessimism and creativity. This dissertation consists of two experimental and two interview

Sustainable development and engineering ethics as well as social aspects of engineering are emerging issues related to power electronics. Several important topics like environmentally sustainable products and electromagnetic compatibility fit into this description. Therefore, these issues have recently become part of the advanced course on power electronics at Lund University. The authors' intenti
